M600 Filament Change option

Marlin Firmware Service Firmware Builder
1

I would like the ability to add this option when building my firmware. Can you add this?

If you add the filament run-out sensor when building the firmware that will add the change filamate options in the firmware. You will need to make sure you add M412 S0 to the Start G-Code if you do not have a filament sensor. This will disable the non-existant filament sensor.

There are 3 options under the enabling of the filament runout sensor:

  1. Motion Based Sensor (eg BTT Smart Filament Sensor)

  2. Use HIGH signal for out of filament

  3. Use LOW signal for out of filament

Does it matter which one I choose?

4

Yes - it needs to match the type of filament runout sensor you have.

If you don’t have one, and you’re just going to disable the sensor, then it doesn’t matter.
